The manure treatment tank 22 is made of metal or plastic and has a cylindrical shape, and is arranged vertically on the floor of a building, and a wooden strip 40 (described later) is placed and loaded therein. . The urine treatment tank 22 is convenient for maintenance if it is provided with a wheel 39 so as to be easily pulled out of the building 21.
[0015]
The upper end of the manure processing tank 22 is open, and this opening is covered with a cover plate 41 that can be attached and detached. A hole (not shown) for the toilet bowl 24 is formed in a part of the lid plate 41, and the toilet bowl 24 is attached on the lid plate 41 in correspondence with this hole. Further, a through hole is formed at the center of the cover plate 41.
[0016]
In the center of the manure processing tank 22, a rotating shaft 30 for stirring arranged in a vertical direction (vertical direction) is rotatably provided. The rotating shaft 30 for stirring is attached to a lower portion of the rotating shaft 30 for stirring. A stirring blade 31 that rotates together with 30 is provided.
[0017]
As shown in FIG. 6, the agitation rotating shaft 30 includes a main body portion (hollow tube) 17 having a hollow portion, an intermediate shaft portion 18 having a hollow portion on the main body portion 17, and the intermediate shaft portion 18. It is integrally formed with an input shaft 19 that is above and has a hollow portion. The hollow portions of the main body portion 17, the intermediate shaft portion 18, and the input shaft 19 of the rotating shaft 30 for stirring are in communication with each other.
[0018]
The intermediate shaft portion 18 and the input shaft 19 of the stirring rotary shaft 30 extend upward through a through hole formed in the center portion of the lid plate 41. An upper bearing 37 and a lower bearing 38 are installed above and below the agitation rotating shaft 30. The upper bearing 37 is disposed on the cover plate 41 so as to correspond to a through hole formed in the center of the cover plate 41, and supports the stirring rotary shaft 30 so as to be rotatable at the intermediate shaft portion 18. Yes.
[0019]
And the lower side bearing 38 is arrange | positioned in the bottom part of the manure processing tank 22, and is supporting the rotating shaft 30 for stirring rotatably at the lower end. Below the stirring rotating shaft 30, the stirring blade 31 is symmetrical about the rotating shaft 30 for stirring so that the stirring blade 31 is parallel to the bottom of the manure processing tank 22 (left and right in the radial direction of the manure processing tank 22. Installed symmetrically).
[0020]
The stirring rotary shaft 30 is rotationally driven by a motor 27 with a speed reducer for stirring driving. The reduction gear-equipped motor 27 is a known motor and includes a motor body 43 and a gear box 44 having a reduction gear. A gear box 44 is supported by the support arm 42 and is provided above the cover plate 41 corresponding to a through hole formed in the center of the cover plate 41.
[0021]
The rotation of the motor main body 44 is configured to be transmitted to the output shaft 45 in the gear box 44 via a reduction gear mechanism and a transmission gear mechanism (not shown). The output shaft 45 is a hollow shaft as shown in FIG. 7, and is placed vertically (arranged in the vertical direction) in the gear box 44 and is rotatably arranged.
[0022]
In the hollow portion of the output shaft 45, the input shaft 19 of the stirring rotary shaft 30 is inserted and fixed. Thereby, the rotation of the motor 27 with a speed reducer is transmitted to the rotating shaft 30 for stirring, and the stirring blade 31 is rotated together with the rotating shaft 30 for stirring. The rotation speed of the stirring blade 31 is set to around 1 rotation per minute, but may be set by changing an appropriate rotation speed according to the use environment.
[0023]
The stirrer blade 31 has a reinforcing frame 32 attached symmetrically to the lower part of the rotating shaft 30 for stirring, and the strength of the stirrer blade 31 is enhanced. The reinforcing frame 32 is formed of a material such as a metal tube having a hollow portion, and the cross section thereof is, for example, a rectangular frame.
[0024]
The reinforcing frame 32 is attached to the lower part of the agitation rotating shaft 30 so that the hollow part communicates with the hollow part of the agitation rotating shaft 30, and supplies air into the manure treatment tank as will be described later. It also functions as an air pipe. The reinforcing frame 32 is a surface on the opposite side to the rotation direction of the stirring blade 31 (when the rotation traveling direction of the stirring blade 31 is “front side”, the opposite side to the rotation direction is “rear side” or “back side”. )), A plurality of air discharge holes 46 are provided along the longitudinal direction thereof (provided at intervals).
[0025]
As shown in FIG. 5, the stirring blade 31 is reinforced by the reinforcing frame 32 and is formed so as to extend symmetrically along the bottom of the manure treatment tank 22 (parallel to the bottom). And the stirring blade 31 is inclined and formed toward diagonally upward on the opposite side (rear side) to the rotation direction. That is, the stirring blade 31 is attached to the bottom portion of the manure treatment tank 22 so that the upper portion is inclined from the vertical to the opposite side with respect to the rotation direction, that is, the opposite side of the rotation direction by 45 degrees.
[0026]
Further, the stirring blade 31 is configured by bending at one or a plurality of locations and bending it. Further, on the upper part of the stirring blade 31, a plurality of projecting pieces 47 are projected in the longitudinal direction of the stirring blade 31 to form an uneven portion 48. Since the stirring blade 31 has such a structure, when the stirring blade 31 rotates, it operates to scoop up the wooden strip 40 while moving the wooden piece 40 radially outward of the manure treatment tank 22.
[0027]
Further, tail blades 34 and 35 are attached to the rear side (back side) of the stirring blade 31. The tail blades 34 and 35 are attached so as to be inclined from the portion fixed to the stirring blade 31 toward the stirring rotary shaft 30, that is, toward the center of the manure treatment tank 22. Thus, the wood strip 40 scooped up and dropped while moving outward in the circumferential direction serves to bring the stirring rotary shaft 30 side, that is, to the center side.
[0028]
Further, a scraper plate 33 is attached to the tip of the stirring blade 31, scraping off the wooden strip 40 adhering to the inner surface of the side wall of the manure processing tank 22, so that the wooden strip 40 is the inner surface of the side wall of the manure processing tank 22. Prevents from adhering to and growing.
[0029]
A heater 36 is provided in order to heat the inside of the manure processing tank 22 to an optimum temperature that promotes the activation of microorganisms. The heater 36 controls the temperature of the wood strip 40 to a preset temperature with a temperature controller in order to obtain the optimum temperature.
[0030]
A blower 28 is disposed on the lid plate 41. The blower outlet of the blower 28 is configured to communicate with the hollow portion of the input shaft 19 via a blower pipe 49 and a universal joint 29 provided at the upper end of the input shaft 19. The input shaft 19 is configured to rotate relative to the universal joint 29.
[0031]
Thereby, the air sent from the blower 28 through the blow pipe 49 is supplied from the universal joint 29 through the input shaft 19, the intermediate shaft portion 18, and the main body portion 17 of the stirring rotary shaft 30 into the reinforcing frame 32, and is reinforced. A plurality of air discharge holes 46 formed on the back side of the frame 32 are discharged to the opposite side (rear side) of the rotation direction of the stirring blade 31.
[0032]
A ventilation duct 50 is disposed in the building 21. The ventilation duct 50 extends from the cover plate 41 to the upper portion of the building 21 so as to communicate with the manure treatment tank 22 through a through hole formed in the center of the cover plate 41. A ventilation fan 26 is arranged in the middle of the ventilation duct 50. As a result, it is possible to suck the gas decomposed by the microorganisms directly from the inside of the manure treatment tank 22 covered with the cover plate 41 and exhaust the gas to the outside of the building 21.
[0033]
In this case, since the exhaust amount from the ventilation fan 26 is larger than the gas generated from the manure treatment tank 22, the inside of the building 21 becomes negative pressure, and the air in the toilet room is also sucked from the upper part of the hole of the toilet 24. It is possible to prevent the odor from being smoked in the building 21.
[0034]
The wood strip 40 (wood chip) serves as a so-called dwelling place where microorganisms parasitize when microorganisms that decompose manure are applied and the microorganisms settle and propagate. As general-purpose products, there are cedar chips and sawdust (sawdust). Usually, the wood strip 40 is formed by using wood sawdust or the like as a raw material and solidified to a size of about 1 cm.
[0035]
Although the chemical composition varies depending on the type of raw wood, it is preferably 60 to 65% cellulose, 15 to 25% lignin, 10 to 15% pentozan, and 11 to 16% moisture. It is preferable that the wood strip 40 is loaded by loading about 50 to 70% with respect to the volume of the manure treatment tank 22. In addition, it is not necessary to stick to plants, such as the wood strip 40, and charcoal, tochihu or ceramics can be used.
[0036]
Two indicator lights 51 and 52 are provided on the side of the entrance door 16 to display the usage status and the driving status of the toilet 15. Specifically, the indicator lamp 51 is configured to light only “in use” (not “not in use”) so that it can be determined whether or not the toilet is in use. The indicator lamp 52 is always lit during operation and blinks when there is an abnormality in the facility so that the toilet 15 can be recognized as being in operation or out of order.
[0037]
Then, when the indicator lamp 52 blinks when the equipment is abnormal, each part blinks at the time of failure in order to display in detail so that it can be confirmed in detail in which part of the equipment the failure has occurred. For example, warning lights such as “stirring system”, “blower system”, “heater system”, “inverter system”, and “sequencer system” are incorporated in the control panel 23 or provided in the vicinity of the control panel 23.
[0038]
A human detection sensor 25 is attached inside the building 21 and detects when a person enters the toilet room, and only the rotational drive of a stirring blade 31 described later is stopped to ensure safety. The indicator lamp 51 on the side of the door 16 is turned on to inform the next user that the toilet 15 with urine processing tank has already been used.
[0039]
A control plate 23 is provided in the toilet 15 with the urine processing tank. The control plate 23 is provided with a sequencer, a temperature setting device, an inverter, a circuit board, and the like for controlling various operation systems such as an operation timer, temperature control, and indicator light control. A microcomputer may be provided as the control plate 23 to operate the various operation controls.
[0040]
(Function)
The operation of the toilet 15 with the manure treatment tank of the present invention having the above configuration will be described below. When the motor 27 with a speed reducer is started, the rotating shaft 30 for stirring is rotated by the input shaft 19. Then, the stirring blade 31 rotates in the manure processing tank 22.
[0041]
On the other hand, when the blower 28 is operated, the air from the blower 28 is supplied to the reinforcing frame 32 through the blower pipe 49, the universal joint 29, the input shaft 19 of the rotating shaft 30 for stirring, the intermediate shaft portion 18, and the main body portion 17. Then, it is discharged from the plurality of air discharge holes 46 formed on the back side of the reinforcing frame 32 into the manure treatment tank 22 toward the opposite side (rear side) in the rotation direction of the stirring blade 31.
[0042]
When the stirring blade 31 rotates, the upper portion of the stirring blade 31 is attached to the bottom of the manure treatment tank 22 so as to be inclined at about 45 degrees from the vertical to the opposite side (rear side) to the rotation direction. By rotating 30, the wood strip 40 at the bottom of the manure treatment tank 22 is scooped up and lifted up.
[0043]
On the upper side of the stirring blade 31, a plurality of protruding pieces 47 are spaced apart to form a large uneven portion 48, so that the scooped up wooden strips 40 are at different heights opposite to the rotation direction of the stirring blade 31 ( Drop it to the rear side. Further, since there is a space in the immediate vicinity of the rear side (back side) of the rotating stirring blade 31, the upper part of the wood strip 40 opposite to the rotation direction of the stirring blade 31 (rear side) collapses and mixes itself.
[0044]
Further, since the stirring blade 31 is bent toward the opposite side with respect to the rotation direction, when the stirring blade 31 rotates, the wooden strip 40 is scraped upward and the manure treatment tank 22 Can be moved radially outward.
[0045]
As a result, the wood strip 40, which is a place where microorganisms live, is scooped up and moved to the upper side and radially outward of the manure treatment tank and loaded into the manure treatment tank 22 while stirring the top and bottom of the wood strip 40. Can be changed. The wood strip 40 moved to the outside in the radial direction is returned to the inside in the radial direction by the tail blades 34 and 35. When viewed from above, the wood strip 40 rotates in the manure treatment tank 22. While being lifted and dropped, the mixture is further stirred from the outside to the inside.
[0046]
In this way, the wood strip 40 and the manure to be treated are sufficiently stirred and mixed. Furthermore, the air (oxygen) supplied from the blower 28 penetrates into the stirred wood strip 40, and the contact area with microorganisms increases, so that the decomposition efficiency of manure and odor can be greatly increased.
[0047]
Since the plurality of air discharge holes 46 are provided so as to be spaced apart in the longitudinal direction of the stirring blade 31, air (oxygen) permeates the entire urine treatment tank 22 from the air discharge holes 46. The amount of air discharged is approximately 200 milliliters per liter of wood strip in the urine treatment tank 22, thereby aerobic and microorganisms are activated, preventing the vicinity of the bottom in the urine treatment tank 22 from becoming anaerobic. Therefore, the processing amount increases and the odor decreases drastically.
[0048]
The blower 28 is operated only when the stirring blade 31 is rotating, and the air supplied from the blower 28 is sent from the air discharge hole 46 formed on the rear side (back side) of the stirring blade 31 to the manure processing tank. Since the air discharge hole 46 is released into the air discharge hole 46, the air discharge hole 46 is not clogged with the pressure of the wood strip 40 or excrement.
[0049]
Here, the normal driving | running aspect of the toilet 15 with the manure processing tank of the Example of this invention is demonstrated. The operation of the toilet 15 with the urine processing tank is usually an automatic operation.
(B) When the user enters the room, the human sensor detects it, and when the user goes outside the room, he leaves the human sensor and senses it once in about 5 seconds. After that, while there is no user, the stirring is periodically continued by setting a timer.
[0050]
(B) The heater is repeatedly turned on and off according to the temperature setting, but when the stirring blade 31 starts to rotate, the heater is turned off to reduce the maximum power consumption.
(C) The blower 28 is started together with the motor 27 with a speed reducer, and is similarly stopped when the rotation of the stirring blade 31 is stopped.
[0051]
(D) When there is no user for a long time, it automatically pauses to save energy. Although the setting of the time for displaying the unused state is arbitrarily determined, it is desirable after about 24 hours have passed since the excretion disappears. There are three places to stop for energy saving: the motor 27 with a reduction gear, the heater 36, and the blower 28. Even if it is resting as it is, the next time someone uses it, it resumes automatic operation.
(E) If it is determined that the device will not be used for a long time, turn off the power switch and stop it completely.
[0052]
As mentioned above, although embodiment of the toilet with a manure processing tank concerning this invention was described based on the Example, this invention is not specifically limited to such an Example, The technical matter of a claim statement is described. It goes without saying that there are various embodiments within the scope of the above.
